Abstract (en)
A data buffer control unit 44 obtains data from a cache in accordance with a command retained in a command queue retaining a command(s) for reading data from the cache, and a magic ID generation circuit 51 generates a magic ID. The data buffer control unit 44 assigns the data obtained from the cache with the magic ID, writes the assigned data to a data buffer, and returns the magic ID to the command queue. When the data buffer control unit 44 receives a read request and the magic ID which is returned to the command queue, it reads the data, which corresponds to the read request, from the command queue and compares the magic ID assigned in the read data and the received magic ID. If the two pieces of magic IDs compared by the data buffer control unit 44 are not identical to each other, a packet generator detects an error and reports the error to a host apparatus.
